IIWPROVEMENT IN GRADING-PLOW AND SC1'\.AIIEIEE Ir The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern:

-Be it known that I, A. P. HOPKINS, of Bentleyville, in the county of Washington, andSt-ate of Pennsylvania, have invented a new and improved Grading- Plow, or Scraper; and I do herebv declare that the following` is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reierence being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a side riew of my improved plow or scraper, part being broken away, to show the construction.

Figure 2 is a top View of the same.

Similar letters of reference indicate corresponding parts My invention has for its object to furnish'an improved machine for moving dirt, snow, and other suhstances, from place to place, as in grading roads, &c., clearing off snow or dirt from roads, pavements, lYards,

dt consists in the constructioirand combination of the various parts of the machine, as hereinafter more fully described.

A isthe landside of the plow, or scraper, the forward end of which is concail'ed, as shown in iig. l, so that it may have a pointat both its Lipper and lower Thel rear parts of both edges of the landside A are cut' away, as shown in iig. l; and to the forward and rear parts of botli of said edges are pivoted wheels, B,

take hold of the ground, and compel the scraper to more forward in a straight line, or, in other words, with its landsidc in line with the draught.

C is the mould-board or inclined side ofthe scraper, the forward end of 'which is so formed as to correspond with the lforward end of the landside A.

The outer side of the mould-board is concaved or hollowed out longitudinally, as show n in the drawings, so that it may work equally well when the machinef is used with either side up. l

The rear part of the mould-board O is strengthened,

and enabled to resist the side pressure, by a brace or braces, D, interposed between the rear end of the said mould-board O and the rear end of the landsi'de A, as

of the machine, and which is pivoted in the slot ofthe.

slotted lever G.

The forward end of the lever G is connected with the middle part of the rear end of the landside A by a double-jointed connection, H, so that the said lever and wheel may have a free lateral and vertical movement.

The rear end of the lever G extends back, so as to serve as a handle.

The lever G and wheel F enable the landside to be raised, to free the machine, should it become fast when 1n use.

The said lever and wheel .also serve to turn andguide the machine.

It should also be observed that the machine should be made suticiently heavy to cause the teeth or spurs of the wheels B to take a firm hold upon the ground;

so as to keep the landside A in line with the draught.

I claim as new, and desire to secure by Letters Patentl. Constructing the scraper A C D so that'it may be used either side up with equal facility, substantially as herein shown and described.

2. The combination of the toothed or spur-wheels B with the landside A of the scraper, substantially as herein shown and described, and for the purpose set fort-h.

3. The slotted lever Gr and wheel F, iu combination with the rear end of the landside A, substantially as herein shown and described, and for the purpose set forth. A
